In the chaotic multiverse, lost stories abound as events occur across infinite timelines and possibilities. The realm is infinite, with infinite variabilities, making it a fascinating and intriguing concept to explore. Share your ideas in the comments without hesitation, and I will consider turning them into either snippets or short stories. Expect one every couple of days.
Essence of the Human Science God:
You are not an actual god, but you are the peak of humanity in how comic book captain america is a peak human. Your intelligence and understanding dwarfs any of your physical attributes however. You are the super genius, the one who builds an advanced suit of power armor in a cave with scraps, the one they call to fix a hole knocked in space time by an experiment gone wrong. You are probably the smartest person in the room in almost any given situation.
You are the equal and likely superior to just about any super genius you could care to name with a few exceptions in knowledge and skill. The technology you can make is beyond the wildest dreams of what any normal scientist could even comprehend. Advanced A.I., earth shattering power armor, reactors that generate cosmic energies, power nullifiers and more. You do however not have a limitless font of wisdom to make sure that knowledge gets put to good use. Your ability to make the 'right' choices in a given situation remains as it was before your apotheosis. You can further reverse engineer magic, psionics, and other things as a technological equivalent.
Optionally you could get this and also be as equally as capable a magic or psionic user making all of your tech magitech or even psitech, hell have psimagitech.
Perfect memory with infinite storage
None of your technology can be successfully corrupted or subverted by another force unless you build or modify it to possess such a weakness.
You are skilled in combat and can defeat anyone less than a supernatural master of combat or someone so strong you just can't hurt them.
Gain ownership of an Earth sized megastructure that serves as your home. It is hidden away in a pocket dimension and safe from most tampering or attacks. It is defended by billions upon billions of absolutely loyal robots. The strongest of these robots are capable of fighting and utterly dismantling individuals with city destroying capability. The megastructure and you are linked with an unbreakable connection and can command it anywhere, at any time, the megastructure is incapable of turning against you.
The megastructure can create and manipulate matter and energy giving you functionally infinite resources as you require. It has factories and matter forges that can create as much equipment and other tech then you could ever ask for.
It has its own habitats for other life if you want to do any collecting.
The megastructure can theoretically hold billions of people to live and work without issue. It is currently uninhabited except by you and your robots.
The megastructure has a gargantuan palace for yourself and anyone you take in, it is beyond luxurious.
It can resurrect any individual if it can scan something of them, i.e. their soul or some physical component. It will automatically resurrect you if you are somehow killed without fail.
It posesses weapons that can shatter fleets of alien starships or make Galactus fuckoff if he is getting hungry. It is tough enough to survive the omniverse imploding with a lot of dents and systems fried afterwards. Don't worry it can self repair, just very slowly if the damage is bad enough.
If you really need to it can move around and act as a FTL capable battle station of doom if you want to go full galactic warlord. The Megastructure can freely open portals or teleport to different locations, universes, dimensions, multiverses, and Omniverses if you aren't wanting to deal with the local Omniverse creator.
It has a one of a kind forge called the Relic Forge onboard which can let you manufacture extremely potent pieces of technology to put fear into cosmic entities. For when you want to arm your Gods with a Mjolnir or Infinity Gauntlet, just in case.
The God part comes in that the megastructure has an additional function. Using its systems it can create transcendent beings that stand head and shoulders over the normal super robots or AI you can make. The God Anvil can let you build or turn others into your own personalized super beings. Making these Gods is not for the faint of heart, each one represents a ripple of power that could destabilize entire settings, they are walking apocalypses. That said they are programed to view you as their beloved creator with an unbreakable loyalty to weather anything and smother you to death in love, whether that be familial, friends forever, or some other type is up to you. Gods are psychologically incapable of even think of betraying you and automatically disregard anything that would even suggest they do so unless you order them. Even then it would make them uncomfortable to say the least. You may even turn yourself into a God and the megastructure will handle the process for you. A Gods vital essence (soul) is stored in the megastructure so even if they are killed you can simply recall their vital essence of being and slap it in a new vessel. Gods properly designed can threaten or even thrash cosmic beings.
Gods not in use can be put in storage pods where they will hibernate unaware until called back into service. Individuals converted into Gods, new Gods, or resurrected Gods are automatically placed in storage once completed or restored. You can set or modify the traits, attributes, powers, personality and every other facet of your Gods when they are in storage.
Essence of the Involate Self
Drinking this essence confers you the blessing of inviolability of the body, mind, and soul:
You no longer need to eat, drink, breathe, produce human waste, or sleep, and are immune to the harmful effects of radiation alongside extreme environments ranging from the bottom of the ocean to the vacuum of space.
Total immunity to all forms of poison, sickness, or disease, mundane or otherwise. Any existing ailments of a physical, mental, or spiritual nature that plague you will be completely cured upon drinking this essence.
You are biologically immortal and utterly tireless, possessing unlimited stamina - you will be aged/reverted to your physical prime, but no longer age further.
Infinite willpower to keep going through any amount of hardship; even bloody and broken you will not stop, and you will forevermore be protected from the effects of despair, boredom, ennui, etc., that will make living forever a pain in the ass.
Your freedom is also inviolate, protecting you from being imprisoned, copied, incapacitated, trapped, bound, sealed, etc., against your will, automatically freeing you from such situations and teleporting you to the nearest safe location.
Essence of the Tinker of Imagination:
You are now a Worm kind of Tinker, without the Shard itself and instead being an innate part of you.
But unlike a normal Tinker that has a certain specialty or focus, you don't have something so minuscule. No, what you have, is the ability to create any kind of technology you can imagine. You only have to think "I want to create X", or just imagine something, and you will find your power feeding you the knowledge of how to make it. This allows you to create anything you want as long as you can imagine it and it has something to do with technology or science, even things from fiction.
Say you want to make an energy generator the size of a button that produces infinite energy, then your power will not only show you exactly how you make it, but will also guide you in creating it, sometimes entering a fugue state during the process. It will also guide you so that anything you create will fit whomever or whatever you create it for, or anything similar that allows you to actually use the technology how you intended.
You only have to imagine the technology/science, you don't have to know how it works. And if the idea is not physically or realistically possible, your power will still guide you in how to succeed in creating it, imbuing it with a reality bending effect to make it work. No piece of technology or anything from the hard sciences are beyond you, from Time travel to cybernetics to cloning to interplanetary energy systems to Dyson Spheres. As long as you can imagine it and it is based in technology/science, you can make it.
If you wish to fix flaws you find in the original design, your power will help you by feeding you the solution and helping you change the design so that whatever you don't want to happen won't happen. It will also help you prevent possible flaws in tech you create that could have unforeseen consequences, feeding you the information on what the consequences might be. Not only that, your ability also helps you improve upon anything you build, allowing you to endlessly improve your technology.
You are able to instantly understand and reverse engineer any form of technology and science you come across, should you want to.
If you have a form of magic, you are also able to create Magitech.
You are able to create machines that will help you in creating your tinkertech. This can be drones that will automatically create large constructs you upload the blueprints for, or it can be entire factories that can mass produce anything you want. Any machine you create to help you tinker will be able to conjure anything they need to create the technology, from metals to plants and anything else.
You have the ability to control whether your designs are easily reproducible or completely blackboxed, or anything in between. You can also make it so that some can understand and study your tech while others cannot. You can both give and take away the ability to understand your tech should you want to, and this can be done anytime.
You are able to conjure anything you need for your tinkertech, but anything you conjure can only be used for whatever you are creating. And it can only be in parts, as you cannot conjure finished pieces. This means you cannot conjure a finished Drone, but you can conjure a finished battery that the drone needs, unless you want a special battery, in which case you need to make it yourself. You don't have to make every part yourself from scratch, you just can't instantly create your creations. You have to assemble them yourself.
You are completely immune to any attempt to forcefully change, control, copy, or manipulate your body, mind, and soul against your will in any fashion, no matter what method is attempted or used. Those who use supernaturally boosted persuasion are equally stymied, being forced to rely on simple mundane arguments against you as anything beyond that flatly fails to work. You are also immune to memetic effects or the maddening effects of eldritch beings or phenomena.
Your soul cannot be targeted as a vector of attack - the only thing you are still vulnerable to will be actual physical violence if such things can cause damage to you.
No Oracles or any other form of precognition can account for you, ever. Any predictions that are made will be made without taking you into account, and if seeking you out directly, all they get is static. In addition, you are not bound by fate anymore; your destiny is only what you make of it. This extends to the point that people and events that are deemed unstoppable or even unkillable, just because they are destined to, can be killed by you permanently.
You are also immune to reality-warping shenanigans, such as being caught in time paradoxes, time stops, not existing due to someone killing your mother when she's pregnant with you, etc. - your very existence is inviolate.
Note: You can still be injured or killed through direct physical damage if such things are capable of damaging you; all this Essence does is prevent your body, mind, and soul from being affected by other forces without your consent.
Essence of Progenitor Human:
Become the origin point of humanity, the first and greatest human. Gain a body that is vastly superior to that of any normal human in all attributes. You can develop any ability innate to other versions of mankind such as those that are from alternate universes if you come in contact with them. Things like bloodlines, strange powers that can develop naturally and so on. These abilities will grow to match your level with enough time and effort.
Immune to poison and disease. You are also ageless and immune to the ennui caused by the passage of time.
You can create resources from nothing and how they manifest, such as forcing pillars of gold to shoot from the ground as massive landmarks or flooding a depression with fresh untainted water turning it into a pond. Even plants and animals except other sapient beings may be created in the same manner.
Extremely charismatic on the level of whipping up strangers into a frenzy with a few choice words and easily gaining die hard loyal supporters with little effort. Humans especially will see you as a symbol of the species and rally to you should you take up a cause. Even beasts and monsters are not immune as any may be overwhelmed by your mandate to rule nature.
You learn extremely quickly, taking in months of experience in days, years of experience in weeks and decades if not a century of experience in years.
Can survive and thrive in desperate situations and adapt accordingly even if logically you would most likely die an ignoble death.
Can learn and understand anything with enough study, even reverse engineer and reproduce strange alien devices or magical artifacts with human sciences.
Similarly you can uplift more primitive groups of humans to the standard of science and technology that you understand.
Can breed with anything and still somehow result in a viable half human hybrid that takes more after their human side then alien. Toggleable
